You don't really give us enough information to guess here. (My initial
reaction is: that can't happen!)

But we'd appreciate a bug in bugzilla, with:

 - Your GTK+ version
 - Information about your operating system (what distro and version,   
   if Linux)
 - Information about your X server
 - The output of 'xdpyinfo' as an attachment

See the GTK+ README file for more information about filing bugs.

Regards,
